It works

At the first signs of what was either powdery mildew of some kind of blight I sprayed my tomato plants. Had to reapply in the course of a week to make sure I covered all affected areas which I didn't initially see. But after two weeks the mildew/blight has either completely disappeared or subsided. I will have to either get more of this spray bottle or a bigger quantity for the rest of the season. Can't think of a con... but maybe that the spray nozzle could be configured to spray finer droplets so that the liquid does not end up dripping from the leaves but stays on. At the same time, if one sprays from a bigger distance to cover more plants the higher volume discharged is welcome.

It works!

When used consistently, this fungicide can stop and get rid of blight. I used it on my tomatoes in combination with pruning the effected/dead leaves and saw results almost immediately. The blight stopped spreading and after about 2 weeks of use (every other or every 3rd day), it was completely controlled. I had new fruit that was ripening as its supposed to. I bought it to use in conjunction with another fungicide but don't think I'll need the secondary (more powerful) treatment. This stuff did the trick!
